chore: add AngleSharp dependency and refactor rant scraping to use CSS class queries

- Add AngleSharp NuGet package version 1.1.2 to csproj for HTML parsing
- Introduce DomQueryClass helper method using AngleSharp to extract elements by CSS class name
- Replace XPath-based node selection in get_rants with DomQueryClass targeting "rantlist-title-text"
- Update Program.cs to await RunIt task and add a 100-iteration loop around rant fetching
- Add transform string concatenation utility method to Program class
